In theory you could tinker further using this method; reducing the voltage further may allow for cooler running, and you may have more luck in increasing frequency, it really comes down to the “silicon lottery”! Which got me looking at voltages and the BIOS had the CPU at 1.45ish for god knows what reason. What makes you think this Mobo is below than average quality? These voltages are perfectly safe for your CPU but I understand why you are concerned as they are higher than they need to be for normal smooth running. Then they run hot. like this. hi I have doen a fresh clean install of Windows 1903 Installed iCue software on 30th September from Corsair website After installing the icue software voltages on CPU go from 1.0v-1.1v to 1.3v-1.4v When i kill icue voltages return to normal. This is due to both the Ryzen 2000 and 3000 series of CPU s having their voltages set notoriously high by the BIOS. Now at the bottom click on "Save Profile" and then click on "Apply & Test" and the system will reboot. With the H100i, I topped out at 4.4GHz with a 1200MHz memory clock and voltage set at 1.5V. so a 20 thread intel at 5.3ghz still loses to a 3900x at 4.3ghz on 24 threads i would really thought the ground would been made up with the 1ghz more clock speed per core. Ryzen 3xxx CPUs tend to run at veery high voltage even on idle. The 3,800 MHz & Cas Latency 14 is an extremely impressive combination at 32GB with such low voltage. Normally 1.45 is where voltage starts to be a problem causer, as running this voltage over long periods can degrade the CPU faster than normal. I recently put together a Ryzen 9 3900X system with a Gigabyte Aorus X570 Elite Wifi motherboard, 32 GB of G.Skill RipJaws 3600Mhz CL16 RAM, and a Scythe Fuma 2 cooler. AMD Ryzen 3900X I use reaches a boost frequency of 4,500 MHz and usually operates around 4.20 - 4.25 GHz on all [or most] cores. These targets and hopes are somewhat based off our success with overclocking the Ryzen 1st and 2nd Gen. CPUs as well as the Threadripper processors, which you could argue are more akin to the 3900X. Price? I just noticed that temps were idling at 70ish and immediately hitting the 95c thermal limit on load. AMD Ryzen™ 9 3900X desktop processors from the AMD 3000 series are the most advanced desktop processors in the world for elite gamers. Low 50s on idle. 7nm Zen2 processors have arrived. In power save profile the chip idles around 40 with my room being about 29c right now. My cpu voltage is set on auto, I read about it and it seems to be okay and in Ryzen Master it doesnt show as 1.4 anyway. I am talking identical setup other than the CPU 3600 vs 3900x in the Asus setup. Asus board will idle in 1.4v mostly, yes it does dip to sub 1v but lot less than asrock board. It does support 3900x cpu in specifications. Has it failed before? … I have seen various youtube videos about BIOS settings but also about people using ryzan master in combination. The 7nm revolution has arrived, join us as we review the new Ryzen 7 3700X & Ryzen 9 3900X processors from AMD. (plus my previous SSD and an EVGA GTX 1060 3GB) Overall I'm very happy with … Ze zijn sneller, zuiniger en even duur als hun directe tegenstanders, maar goedkoper dan hun prestatieconcurrenten. AMD Ryzen 9 3900X and Ryzen 7 3700X Review: Zen 2 and 7nm Unleashed First 7nm CPUs bring the power. Just rarely for 1 second during a boost. Depends on if any applications you use see benefits from bumping that 3.8 up to a 4.15. Certain settings in BIOS when set ,do not get reported on desktop correctly with third party software but the voltage will still be the same as set in BIOS. Check your voltage if you run high temps on idle!!! I heard Steve at Hardware Unboxed toasted his 3900x because of voltages and the chip is dead. 3900x - Danger High Voltage - Epic Wins - Roshtein - Forum ... Birke420 How do you guys overclock a 3900X? So here's mine: Cooler: custom loop ek strike cpu block Batch: not sure Voltage: 1.25-1.30 depending on load under 65c in everything but prime95. Like way too high. I guess pushing things too much is an asus thing. Any you recommand any BIOS settings or Rzan Master settings? Ok, Im gonna do another post about this because I really want to fix this issue, the thing that I want is simple, I just want my voltage to drop in idle, I dont want to use 1.4 when browsing and things like that. It runs an AMD Ryzen 3900X on an Asus ROG Strix X570-E Gaming mainboard, a DARK ROCK PRO 4 air cooler and 4 fans in the chassis. Reactions: Nightfire, Ebernanut, Nobu and 1 other person. Hey guys, I'd like to get the maximum out of my 3900X - looking into a min. Check with CPU-Z to get the voltage you are looking for that will match what you set in BIOS. Under heavy load the 3900X can run at 1.1v with vdrop which is a great CPU. Even when using supposed “safe” voltages as a maximum input limit for overclocking via BIOS, it’s possible that the motherboard is feeding a significantly different voltage to the CPU. The 3900X ships with a base clock of 3800MHz and a single-core boost clock of 4600MHz, so a reasonable target, with a sensible boost to voltage, would be around 4.3 - 4.4GHz across all cores. AMD Ryzen 3900X Corsair RM750X (niet 2018 variant) Mijn moederbord heeft voor de CPU zowel een 8-pin als een 4-pin connector, ... Lagere kwaliteit silicon > hoge voltages om zelfde freq te halen en 't amd boost algoritme 'weet' hoeveel voltage hier binnen dan 'safe' is. I read a guide somewhere and set all cores to 4.5ghz and set a static voltage of 1.3v until someone told me Id possibly degrade my chip by doing that (had it … 1. I noticed a number of sites and channels are reporting that the AMD Ryzen 9 3900X 12-core, 24-thread processor can be run at full clock speeds with just 1.00V on the CPU VCore. 2. Ryzen 3900X voltage Hello, I recently acquired a 3900x CPU and I am experiencing several cases that I do not know if they would be normal. Hi i currently have my Ryzen 3900x OC to 4.2ghz with 1.1volts. ASRock X370 Taichi. In POV-Ray, running the 3900X at a flat 4.3GHz at 1.35V gives it a 8.2% performance boost over stock. AMD's 3700X en 3900X hebben alle andere troeven in handen. In my opinion, the XMP profile doesn't make sense, though, as you will actually see a gain in performance when you lower the speed to 3,600 MHz (as I have hammered down your throat this whole article). Learn more! Is that safe? Hi, my PC was was configured and built by a local PC dealer. Why don’t you read through this forum thread and see if it can answer your question? I know it is like lottery though. They were both stable at 4.35 GHz, the 3900X needed slightly less voltage at 1.4 V where the 3700X needed just a touch more up to 1.45 V. The happy medium was found to be 4.2 GHz where they would both run stable and cool with only 1.25V and just like the previous generations the voltage scaled quickly as the frequency went up from there. I updated the BIOS to the latest version, AMD Chipset, AMD Balanced power. 1.2 is totally safe. I have never overclocked a AMD. By Paul Alcorn 21 November 2019 As I said, swapping out the CPU cooler enabled me to push the Ryzen 9 3900X harder and faster, but failed to reach the advertised maximum boost clock of 4.6GHz. 4,3 or 4,4 GHz overclock. Ryzen 3900X with a Corsair H100i rad and MX-4 in between. On asrock idle voltages are miles better than asus in windows. You would think that AUTO is the safe bet , no over clocking etc , a base to start from . Ryzen 3900X iCue voltages. After running the benchmark with CTR 1.1 beta 7, it says I can go higher. When the system is not under load then of course the operational voltage will decrease. It depends if you have the voltage hardlocked to 1.2 or Auto. My 3900x was getting fairly low benchmark scores at stock settings, ~6700-6800 in Cinebench R20. The first is the high idle voltage, while idling the voltages do not drop below 1.38v, ranging from 1.44v to 1.38v, although I have to say that this is caused by the iCue software. Setting the Vcore manually to the same value ( 1.2v ) you would think gives the same result , but increasing the voltage the 1.25v gives a better and cooler result to autos 1.2v , So AUTO may be adding a positive offset value somewhere else. My averages are always 1.4v. As you will see, the CPU is limited to a maximum of 1.3 Volts and essentially you are just seeing how much clockspeed you can squeeze out of those 1.3 Volts. I managed to overclock my 3900X to 4.3GHz across all cores – a big improvement from the 3.9GHz I achieved out of the box, but still a little short of AMDs claimed 4.6GHz. Undervolted AMD Ryzen 9 3900X shown be just 23% slower while drawing 36% less power at 1.00V Vcore The Ryzen 9 3900X offers a good scope for undervolting.
